These products provide valuable complementary solutions for applications requiring high-level analog outputs. They are also ideal for situations where the pressure transducer is exposed to conditions detrimental to internal signal conditioning or the required pressure transducer configuration will not accommodate an internal amplifier.

We are proud to offer one of the most comprehensive selections of pressure sensors in the test and measurement industry with ranges from 1 to 100,000 psi and absolute, gage, true gage, differential, vacuum and barometric reference.

We provide pressure sensors with high-level mV/V, analog and digital outputs including RS232, RS485 and CANbus, and accuracies up to 0.05 percent.

We design space-rated sensors for a variety of aerospace applications. These space-rated pressure sensors meet the environmental demands of orbital space flight, as they combine rugged all-welded stainless steel construction and radiation-hardened electronic components to ensure reliable performance throughout the life of the mission.

Stellar Technology’s hammer union pressure transducers are used in many oil and gas applications. These are manufactured with special processes to enhance shock and vibration immunity, which is vital to today’s well servicing environments.

Our sensors include features such as:

Intrinsically safe configurations designed to meet the demanding requirements of hydraulic fracturing in shale oil and shale gas formations

Explosion-proof configurations designed for upstream oil and gas applications to meet BOEM and BSEE regulations

Cutting-Edge Pressure Technology

At Stellar Technology, we are continuously working to develop and use the very latest technology for each of our pressure sensors and transducers. Our hammer union pressure sensors are a perfect example of our continued innovation.

Some of the great features of this technology include:

As part of the next generation of pressure sensors, our hammer union pressure transducer combines a number of unique qualities to create a new and improved system

The all-welded construction allows for long-lasting durability and the seals, with an O-ring inside, help to keep out moisture

We also included a large port that is ideal for a variety of applications, as well as four smaller ports at the top of the mount to allow drainage of liquid no matter how you mount it

The hammer union pressure sensor is EMI- and RFI-protected, as well as shock- and vibration-proof

We even field-tested this product for more than a year before releasing it into the market to test its capabilities and ensure its readiness for you. That’s how dedicated we are to our customers.

How to Select a Pressure Transducer

Before you purchase a pressure sensor, there are a number of factors you should consider. These may range from the amount of pressure the sensor needs to measure to the environment in which the sensor will be used.

We’ve divided these factors into five main categories for you to keep in mind as you search for the right pressure sensor for your application.

1. Performance Considerations

As you begin your search for the right pressure transducer, one of the most important considerations is whether it will perform at the level you require. You need to find a product that has the capabilities to handle your specific application.

2. Mechanical Considerations

Configuration and other requirements, such as small diameter, flush diaphragm, secondary containment or explosion-proof, among others

3. Electrical Considerations

Electrical termination

Electrical output from the sensor - is it analog, digital, or a combination?

External zero and span potentiometers

DIN rail mount or in-line signal conditioning for mV/V units

4. Environmental Considerations

The environment in which the pressure sensor operates plays an important role in the choice of the sensor. In order to receive accurate readings, here are a few things you should keep in mind when choosing your sensor:

Operating temperature range - if not compensated correctly, it can change the readings drastically

Compensated temperature range

Electromagnetic and radio frequency interference (EMI/RFI) conditions

Is an Ingress Protection (IP) or National Electrical Manufacturing Association (NEMA) rating required?
